SIPHON.

Application filed April 28, i915.

To all whom t may concern:

Be it known that l, VVILIJAM T. ANDER- soN, a citizen of the United States of Amen ica, residing at Atlantic, in the county of Cass and State of iowa, have invented certain new and useful .improvements in Adjustable Controllable Siphons, of which the following is a specification.

My invention relates to improvements in siphons having a connected air exhausting cylinder and piston for depleting the air in the bent siphon tube, to start the flow of a liquid therethrough; and the objects of my improvement are, first, to dispose the air exhausting cylinder entirely outside of the siphon duct; second, to provide convenient means remotefrom the end of the discharging leg to stop and start the siphon and control the quantitative rate of flow; and third, to aord facilities for attaching the siphon vertically adjustably over the rim and side wall ot' any open-topped liquid receptacle. These, and other minor ob'- jects and advantages, I attain by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a side elevation showing the siphon applied to partly empty a liquid from a container 1, shown ragmentally in the view; and Fig. 2, an elevation, partly in vertical section, taken at right angles to the view in Fig. 1.

In all of which views similar numerals refer to similar parts.

The discharging leg 2 of an inverted U- shaped siphon has a suction cylinder` 3 juxtaposed parallelly therewith. The open connecting duct 4, disposed across between the bases or the leg and cylinder, serves also as a rigid connecting bridge. A bridge 16 disposed across between the top end of the cylinder and the bend in the top ci the siphon pipe completes means to retain this leg of the siphon and the cylinder in rigid parallel relation best disposed in a plane at right angles to the plane of the bend of the siphon. The opposite or intake leg 5 is disposed telescopically through the clampbase-sleeve 6, to slide endwise therethrough or revolve therein. The spring-actuated setting pawl 7 is pivoted at one side of said sleeve and is adapted to normally engage in the spiral groove 8 cut around in the outer surface of the leg. To the opposite side of the clamp-base-sleeve is attached a strong clamp consisting of the downwardly dis- Speccation of Letters Patent.

posed jointed jaws 9 actuated'by the spring 22 to engage and close on the wall ot any open-topped receptacle,- to support thereon the whole Siphon contrivance. For greatest adjustment or height of the intake leg in the receptacle it is released from the spring pawl and slid endwise in the supporting sleeve. For closer adjustment, to get a particular part or strata of the content of the receptacle, the leg is revolved in the sleeve while the pawl is in engagement with the spiral groove.

The piston 10, in the suction cylinder 3, is carried bv the piston rod 11 disposed to slide through the valve-controlling-sleeve 12, and has at its top end the handle 21 'for manual manipulation. r1`he valve-controlling-sleeve is disposed through the removable cylinder cap 13 to slide vertically and revolve therein and around the piston-rod to allow its manipulating handle 14, at the top, to be turned to any convenient position. A lever 15 is centrally pivoted on the bridge 16. One end of this lever is loosely inserted through a suitable opening 23 in the wall of the cylinder and into engagement between the spaced collars 17 around the inner or lower end of the valve-controllingsleeve. The opposite end of this lever is jointed to the top end of the connecting-rod 18. The lower end of the connecting-rod is jointed to the rocking lever 19 of the cock-valve 2O disposed in the lower end of the discharging leg of the siphon. These connections are so made and constructed that when the controlling sleeve is slid downwardly to the limitas shown in Fig. 2,-either by independent manipulation through the handle 14 or by engagement on top of the sleeve by the downwardlv forced handle Q1 of the piston-rod, the valve is closed. But, when the controlling-sleeve is raised to its limit of upward movement, bringing these connected parts into the positions shown in Fig. 1, and as indicated b v the dotted lines in Fig. 2, the valve stands open for flow of the siphon. This latter position may be attained, either by the upwardly moving piston engaging the lower end of the controlling-sleeve, or manually by the handle 14.

1n operation, the device is first attached and adjusted for height on a receptacle 1, as shown in Fig, 1, and the Siphon-starting parts positioned, as shown in Fig. 2. The cock-valve stands closed while the piston is drawn upwardly to deplete the air in the Siphon duct, which duct thereby is filled with the liquid. The capacity ofthe cylinder is such, that after the Siphon is filled with the liquid the piston engages the controlling-sleeve to .open the valve.` By reverse movement of ythe piston, taking the piston-head out of the range of movement of the sleeve, or by Stopping the upper movement just before the piston-head engages the sleeve, the controlling-sleeve is left free for manipulation by the handle 14, to set. the valvecock in any partially opened position for dierent desired rates Vof flow.`

Y I claim:

l. In a Siphon the combination of an inverted Ushaped duct, a cock disposed in the discharging leg of the duct, a pump cylinder commu-nicably connected with the discharging leg abo-ve said cock, a revoluble longitudinally-slidable sleeve disposed through the head of the pump cylinder, a piston consisting oi' a piston-rod disposed through said sleeve, a piston-head disposed in the cylinder to engage the inner end of .said sleeve and a handle on the outer end of the piston-rod to engage the outer end of Said sleeve, means to connect the sleeve to open and close said cock, and ahandle on the outer end of the sleeve to manually revolve or slide the sleeve independently of the pist0n.

2. A siphonfcomprising communicablyconnected receiving and discharging legs, a cock in the ,discharging leg to open .and close the Siphon duct, a Suction cylinder having one -end connnunicably connected with the discharging leg above said cock, a longi-V tudinally-slidable-Sleeve ydisposed centrally through the opposite hea-d of said cylinder, a centrally pivoted lever `having one end connected to said sleeve and the-'opposite end connected to o-pen vand -cl-ose said cock, anda handled piston having a rod disposed slidingly through Said sleeve, the head of the piston disposed in said cylinder and adapted to engage the inner lend of the sleeve to slide it outwardly, and the handle on the outer end of the piston-rod adafptedto yengage the out-er end of saidk sleeveto slide it inwardly.

In testimony whereof I'have aiiiXed my signature in presenceof two witnesses.
